How old is this David Clarke Astrolabe? Most likely the last number (on mfg. plate) is the internal mfg. serial number, which would suggest a 1945 manufacturing date. http://www.surveyhistory.org/how_old_is_my_david_white.htm greg chicago == Date: Fri, 30 Nov 2018 17:38:12 -0800 From: Brooke Clarke <[email protected]> To: Discussion of precise time and frequency measurement <[email protected]> Subject: [time-nuts] Timing for Pendulum Astrolabe? Hi: I'm learning about the 60-Degree Pendulum Astrolabe: https://prc68.com/I/PendulumAstrolabe.shtml The idea is to mark the time when a known star crosses the 60 degree elevation circle. Is there an Android app where I could just push a button and have the local mean sidereal time recorded?? Lacking LMST is there an app for any other time scale? _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.
